Graphical description of controller. a Per trained movement, a representative steady-state point in feature space is found and assigned a movement label b Representative points are normalized to have unit L1 norm, and Delaunay Triangulation partitions feature space into regions emanating from the origin c The movement label for online EMG is determined by linear interpolation, providing an estimated level of user intent in every DoF (D) A physiologically inspired relation maps estimated levels of user intent to nominal hand velocity. Subject preferences then set gains and thresholds
